WILLIAM SANDERSON, OF NEW YORK, N. Y.

.- IMPROVEMENT IN THE PROCESSES 0E ORNAMENTING COMPOSITION MOLDED ARTICLES,

Specification forming part of Letters Patent No. 146,479, dated January 13, 1874; application filed June 5,1873.

GAsE A.

have invented a new Process of Producing Designs on Composition Surfaces.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings making part of this application.

Previous to my invention checks for restaurants and other places, keychecks, door-numbers, drawer-labels, and a variety of such articles have been made of various patterns, and with designs, numbers, letters, &c., produced by different processes upon their surfaces. In the manufacture of all such articles it is a great desideratum to have the figures or design, whatever itmay be, so combined with or produced on the composition surface as to be-as lasting or durable as possible, while, at the same time, the article can be afforded at the least possible cost. To combine, in the manufacture of all sucharticles, these two advantages in the most eminent degree is the main object of my invention, which, to this end, consists in printing, embossing, or otherwise producing on thin paper the desired design, and then uniting such paperlesign with the composition, check, name-plate, or other article, by the aid of any suitable adhesive mixture, and by subjecting the parts to be united to compression in heated dies, as will be hereinafter more fully descrbed.

y To enable thofseFskilled in the art to make and use my invention, I will now more particularly' describe my new process, referring, for illustration, to the accompanying drawings, in

. whichi I have shown at Figure 1 a c'rcular check,

molded of any of the well-kno n and suitable compositions, in imitation of ivory. At Fig. 2 is a view of a piece of thin' paper with the numberor design printed thereon. At Fig. 3 is a view of a nished check with the number on; andV atFig. 4; is a sectional view, on an exaggerated scale, illustrating the manner in which the parts composing the linished article are combined or put together.

In carrying out my invention, I make the check, name-plate, door-number, or other article by molding it in dies in the usual manner, and from a composition or compound suitable y for the purpose. (Any of the compounds of factitious ivory, or the composition used for making door-knobs and other articles, may be employed in practicing my new process.) I

then take thin paper, either transparent or` semi-transparent by preference, or silk, and either print, cut out, or otherwise produce on or in the paper or silk" any desired design, number, &c., which I desire shall be presented on the surface of; the composition article; and this paper-designI unite temporarily with the surface of the composition with some white shel lac, varnish, or other suitable adhesive material, applied with a brush. I then place the combined elements in the die in which. the

composition was molded, or a duplicate die, v

sometimes use perfectly-transparent paper,`

which is preferable where the design is united with a surface composed of white composition, and the paper-design has a white ground. At other times I, under circumstances, prefer that the paper be only translucent or opaque. In

lieu of paper, linen or other textile material may be used. The design, when printed on the paper, may be made either on the outer or exposed surface of the paper, or it` may be printed in reverse on the surface which is placed next to the composition. In either Way the result is substantially the same. Before subjecting the article to the action of the press in the heated dies, the exposed .or outer surface of the paper may be coatedA over with var nish; but I iind, in practice, that without this the coating or layer of varnish put on between the paper and composition strikes through and produces on the outer face of the paper a polished and impervious face, which protects the design on the paper suiiciently.

It will be understood that, When the composition check a has the paper-design b united or applied, as seen at Fig. 3, its paper surface presents a comparatively rough appearance, and the two parts are simply held together by the interposedcoating of varnish, (illustrated by the heavy black line in Fig. 4,) and that, after subjection to compression in the heated dies, the thin layer of interposed varnish strikes through the paper, the paper and composition become as a solid mass, and the surface of the finished article is highly finished, .both Where the paper and Where the composition present themselves.

It Will be readily understood that, in carrying out my invention, the described process may be employed in the manufacture of an almost innite variety of composition-molded articles, and that the characterof the paper and the nature of thc designs produced may be innumerable.

Having so fully explained the mode of manufacture by which I am enabled to produce such articles with any design of any suitable composition, and so that when finished the article shall possess the qualifications of beauty of appearance with durability, and by which the product can be supplied at comparatively small cost, what I claim as new, and desire to secure by Letters Patent, is

The process hereinbefore described of ornamentin g composition-molded articles,'consisting essentially in combining, With the molded article, (Whatever it may be,) paper having a design printed, painted, stamped, or otherwise placed thereon, the union and iinish of said paper design, and its composition base or body, being effected by compression between heated dies, substantially' as described, for the purpose set forth.
